Hey I'm new here so hopefully you guys can help. I have a 99 explorer an once in a while when it either just idling or when being ridden it will start cutting out like the rev limiter kicks in. When it does it you cannot turn the machine off with the key or kill switch. There is not a certain time it does it. I've changed the key switch, and the switch on the handle bars next is the wiring harness. Any suggestions would be appreciated. Thank you.
